Built or designed with castle-like features, especially crenellations (notched parapets on top of walls) and towers; having the characteristic appearance of a castle.
From Late Latin 'castellatus' (made castle-like), from 'castellum' (castle). The past participle form indicates something that has been modified or created to have castle features.
Victorian architects went crazy for 'castellated' buildings in the 1800s—adding fake battlements to banks, prisons, and even homes. It was the era when 'looking medieval' became a status symbol that proved you were cultured and wealthy!
